Description
Technical field
The utility model relates to a kind of goods stockpile level detecting apparatus, specifically a kind of heap level detecting apparatus for detecting the position, stockyard residing for stocker and reclaimer of goods stockpile field.
Background technology
The raw materials and fuel of a lot of manufacturing enterprise all adopts stockyard to put in order, and both sides, stockyard arrange corresponding stocker and reclaimer carries out daily windrow and feeding work.For a cement production enterprise, its raw materials and fuel stockyard adopts microscler layout, is divided into six Ge Dui districts, and wherein raw coal is in first and second heap district, and auxiliary material is in the 3rd to the 6th heap district.Side, stockyard adopts a domestic elongated side formula cantilever stocker, works in Quan Dui district; Opposite side adopts two director's type side formula scraper reclaimers, and one works in one, two raw coal heap districts, and another works in three to six auxiliary material heap districts, and between two reclaimers, track disconnects mutually.
In microscler stockyard, three chassis run together time, and anticollision is therebetween chain particularly important, once mistake appears in signal, the serious equipment breakdown that stacker-reclaimer is collided just likely occurs in chain inefficacy.Its safety interlocking is the heap position relation based on heap feeding, also the mutual alignment namely between stacker-reclaimer, current domestic general method of inspection is a series of goat's horn limit switches by being arranged on differing heights on stacker-reclaimer, when the collision block interval by two heaps, the action of corresponding goat's horn limit switch, mode of operation changes, and PLC detects each on off state and makes location determination.
Because field working conditions is poor, goat's horn Switch Controller installation site requires again relatively strict, in use often switch malfunction, phenomenon of being failure to actuate occurs, and 5 switches have 36 kinds of different permutation and combination, and arbitrary switch motion mal all can cause the erroneous judgement of heap position.Therefore exist maintenance large, to shortcomings such as maintainer's technical requirements are higher.The most important thing is normally to run to equipment to bring very big potential safety hazard, to collide major accident with regard to there is the stacker-reclaimer that causes because heap bit-errors at the putting equipment in service initial stage.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of goods stockpile field heap level detecting apparatus, it adopts a travel switch to replace original multiple goat's horn switches, improve equipment safety in operation and reliability, greatly reduce the work capacity of follow-up maintenance, ensure that carrying out continually and steadily of production.
The utility model is for solving the problems of the technologies described above, the technical scheme adopted is: a kind of goods stockpile field heap level detecting apparatus, comprise PLC control system, counting machine and multiple goods stockpile district, described multiple goods stockpile districts are strip distribution, track is respectively arranged with in the both sides along its length, goods stockpile district of strip distribution, the track of every side is respectively used to stocker and reclaimer moving back and forth thereon, the position described every bar track corresponding to each goods stockpile district is also respectively arranged with one for triggering the contact block of travel switch, stocker and reclaimer are respectively arranged with a travel switch that can match with the contact block in its respective carter, and each travel switch is all connected to a counting machine, described stocker and reclaimer are also respectively equipped with the direction detector for detecting its direct of travel, described direction detector sum counter is all connected with PLC control system, the count value of the direct of travel sum counter that PLC control system can detect according to direction detector controls the operation of stocker or reclaimer.
Described multiple contact blocks are on same level line.
Beneficial effect:
The utility model adopts a travel switch to replace original multiple goat's horn switches, is monitored by the particular location of detection and control to stocker and reclaimer of impulse singla and is held.Improve equipment safety in operation and reliability, heap bit error rate reduces greatly, substantially reaches non-maintaining, greatly reduces taking society's maintenance strength.Ensure that carrying out continually and steadily of production, achieve good economic benefit.Meanwhile, equipment investment is few, instant effect, and later maintenance amount is little, and operating cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Graphical indicia: 1, PLC control system, 2, counting machine, 3, goods stockpile district, 4, track, 5, stocker, 6, reclaimer, 7, contact block, 8, travel switch.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described:
A kind of goods stockpile field heap level detecting apparatus, comprise PLC control system 1, counting machine 2 and multiple goods stockpile district 3, the distribution in strip of described multiple goods stockpile districts 3, track 4 is respectively arranged with in the both sides along its length, goods stockpile district 3 of strip distribution, the track 4 of every side is respectively used to stocker 5 and reclaimer 6 moving back and forth thereon, the position described every bar track 4 corresponding to each goods stockpile district 3 is also respectively arranged with one for triggering the contact block 7 of travel switch 8, multiple contact block 7 is on same level line, stocker 5 and reclaimer 6 are respectively arranged with a travel switch 8 that can match with the contact block 7 in its respective carter 4, and each travel switch 8 is all connected to a counting machine 2, described stocker 5 and reclaimer 6 are also respectively equipped with the direction detector for detecting its direct of travel, described direction detector sum counter 2 is all connected with PLC control system 1, the count value of the direct of travel sum counter 2 that PLC control system 1 can detect according to direction detector controls the operation of stocker 5 or reclaimer 6.
A kind of goods stockpile field of the present utility model heap level detecting apparatus has carried out technological change to the heap bit switch on stocker and reclaimer, use a travel switch to replace original five goat's horn switches in test section, program uses the add subtract counter function of S7-300, when stocker is by heap position collision block corresponding to corresponding goods stockpile district, heap position collision block touches the heap position that car body is installed and detects travel switch, travel switch action sends an impulse singla, according to stock ground actual arrangement situation, goods stockpile field meeting direction along ng a path successively coding is 1, 2, 3, 4, 5, 6 when car body complies with the direction running of coding numerical value increase along track, PLC control system often receives a heap digit pulse signal control counting machine and adds one, when car body is along track backward going, PLC control system often receives a heap digit pulse signal control counting machine and subtracts one, then the current displayed value of counting machine is true reactor position.
Because the utility model adopts a travel switch to replace original multiple goat's horn switches, reliability has had raising fundamentally, substantially reaches non-maintaining.From transformation in 11 years so far, except human element, there is not heap bit-errors phenomenon again, greatly improved equipment reliability of operation and safety, achieved good economic benefit in business equipment.Greatly reduce the work capacity of follow-up maintenance, ensure that carrying out continually and steadily of production.This technology can be promoted in the industry of pass, can overall raising equipment safe in operation, greatly can reduce taking society's maintenance strength.
